The oxidation of the sugar glucose, C6H12O6 (MW = 180.18 g/mol), is described by the following equation:
C6H12O6(s) + 602(g) → 6CO2(g) + 6H2O(1)
AH = –2816 kJ
How much heat in kilojoules can be produced by the metabolism of 4.7 g of glucose?

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
